Porvair Assay Plates

Porvair assay plates are specifically designed for absorbance, fluorescence, and luminescence applications and are available in 24, 96 or 384 well formats. The plates are made from pure polystryrene for low background to enhance the accuracy and sensitivity of results. The plates are moulded in either clear, black, or white colours and are available with solid bottoms, or assembled with clear polystyrene, glass, quartz or COC bases. These can then be further treated to create specific surface characteristics for cell culture or assay applications.

Features

ANSI-SBS Footprint
Compatible with automated systems
Uniform external dimensions and tolerances
For top reading instruments use a solid white plate for absorbance measurements and solid black plate for fluorescence readings
For bottom reading instruments use clear bottomed plates
Visible wavelength range (900 - 350 nm) measurements require clear plastic bases
Readings between 220 - 350 nm require a UV-transparent material such as quartz or cyclo-olefin co-polymer (COP/COC)
Optical glass sheet is used where visible range detection is combined with confocal optics or whole plate imaging
Manufactured from polystyrene with no additives
Flat bottoms give high surface areas, round bottoms for good mixing, or V-wells for high liquid recovery

Specifications

Absorbance Assays

	Application	Recommended Plate
Top Reading Instruments	High signal from majority of wells e.g. test kits, ELISA	Use simple solid clear plates
Top Reading Instruments	Low signal from some or all wells e.g. kinetics or genetic marker assays	Use solid white plates to boost the signal
Bottom Reading Instruments	Normal visualisation	Use white plates with clear plastic bottoms
	Confocal visualisation	Use white plates with glass bottoms
	For very sensitive assays	Use zero crosstalk white plates with individual clear wells

Fluorescence Assays

	Application	Recommended Plate
Top Reading Instruments		Use solid black plates
Bottom Reading Instruments	Visible wavelength range 350-700 nm, high signal from majority of wells e.g. GFP, Reporter Gene kits	Use black clear-bottomed plates
	Low signal from some or all wells e.g. poor sensitivity assays, low specificity	Use black Zero crosstalk clear bottom plates to boost the signal to noise
	UV wavelength range 220-350 nm	Use black clear-bottomed COP plates
	Confocal or whole plate imaging	Use black glass-bottomed plates

Luminescence Assays

	Application	Recommended Plate
Top Reading Instruments	Good signal	Use solid white plates
Top Reading Instruments	Poor signal or high dynamic range across the plate	Use solid black plates with white wells
Bottom Reading Instruments		Use white clear-bottomed plates
